Latest Key Points of the Dutch Pea Greenhouse Cultivation Technique Tutorial
The Dutch pea is an annual twining herbaceous food plant, and it has a very large planting area in our country. The nutritional value of the Dutch pea is very rich, containing various common nutrients such as protein and carbohydrates. It also uniquely contains a phytohemagglutinin, which can promote human metabolism. So today, the editor will introduce to you the key points of greenhouse cultivation techniques for Dutch peas. Let's take a look below!
1. Land preparation and sowing
The sowing method for Dutch peas is generally direct sowing. Before sowing, sufficient base fertilizer should be applied per mu, mainly farmyard manure, along with compound fertilizer. Deeply level the soil, then make ridges and beds. When planting, in order to improve the germination ability of Dutch pea seeds. Before sowing, the seeds should be sprouted, then soaked in water for about two hours, and then kept at a temperature of about 6 degrees for about a week. When the sprouts grow to about 5mm, they can be sown. After sowing, water promptly, control the plant and row spacing well, and cover the soil to keep warm.
2. Field management
Field management work for Dutch peas is also very important. During the period from after sowing until before emergence, we do not need to water, to prevent the seeds from absorbing too much water and splitting, which would reduce the emergence rate. After the seeds successfully break through the soil, they enter the vegetative growth stage. At this time, pay attention to doing good work in intertillage and weeding, water appropriately, and just keep the soil moist without drying and cracking. When the branches and vines of the Dutch pea plants grow to about 30cm, set up trellises to satisfy the climbing habit of Dutch peas. Then pay attention to watering. During the bud stage, use small water drip irrigation, and stop watering when entering the flowering stage.
3. Appropriate fertilization
Because Dutch peas have strong nitrogen fixation ability, when planting, the demand for fertilizer is not very great. However, this mainly also depends on the variety. Many Dutch pea varieties have relatively strong growth ability and relatively high planting density. Therefore, when planting, appropriate topdressing should also be done. For these varieties, about three topdressings are needed throughout the entire growth period. Carry out the first topdressing during the vine drawing stage, mainly with farmyard manure. Then apply phosphorus and potassium fertilizer during the pod-setting stage to improve the plant's disease resistance and increase the pod-setting rate.
4. Pest and disease control
Pest and disease control for Dutch peas is also an important cultivation point. During the planting period, we should focus on doing good work in pest and disease control. In addition to topdressing phosphorus and potassium fertilizer, we should also frequently observe the growth of Dutch peas, regularly disinfect the field, eliminate the base number of pathogens in the field, and avoid some unnecessary losses. Then do good management work, prune diseased branches and leaves, and water and fertilize reasonably. When abnormal conditions are found in the plants, promptly check the specific cause, then take relevant measures.
The above is a brief introduction to the key points of Dutch pea greenhouse cultivation techniques. The cultivation technique of Dutch peas is actually not very troublesome; just do some basic management work. That is all for today's introduction. This article is for reference only.
